ABSTRACT:
A side-mounted pull-rope recoil starter for low horsepower, vertical crankshaft internal combustion engines in which a starter gear moves vertically in a pair of journalled slots in the starter mounting bracket into engagement with a ring gear carried by the engine flywheel. The starter includes a starter brake spring which is released when the starter gear engages the flywheel, an operator handle which is specifically contoured to be comfortably held by the operator during pulling of the starter rope and a mechanical interlock between the engine and a drive transmission to prevent engagement of the starter mechanism when the transmission is in other than the neutral position. A safety lock mechanism which is operable by means of a removable key and which prevents unauthorized activation of the starter mechanism is also disclosed. A top-mounted pull-rope recoil starter is disclosed which incorporates many features of the basic side-mounted starter embodiment.
